JERSEY, A CQRPORATIQN or MOUNTING FOR GAR-AXLE BOXES.

Application filed August 2,

To all whom it may concern: 7 i Y e it knownthat I, JAMES E. BUSHNELL, acitizenof the United States, residing at Cold Springs, county of Putnam,and State of New York, have invented certain new and useful Improvementsin Mountings for Car-Axle Boxes, fully described and represented in thefollowing specification and the accompanying drawings, forming a part ofthe same. y

The present invention relates to certain improvements in the mountingfor car axle boxes set forth in my application No. 382,318 filed May 19,1920, for patent on car axle mountings.

ln that prior construction the car axle boxes were secured upon achannel-bar near its opposite'ends, and were held at the desireddistance apart by the projection of wings upon the boxes into notchescut in the flanges of the channel-bars.

It is the object of the present invention to avoid the labor of cuttingsuch notches in the channel-bars, and at, the same time to provide meansfor holding the boxes securely to thebars, and preferably with clearancebetween the parts, to permit the selfadjustment of the boxes in linewith the axle.

These objects are attained by securing to the bar-flanges at oppositesides of each box, housings which have sockets to engage wings on thebox and hold the box to the channel-bar while permitting self-adjustmentof the boxes.

The wings are offset toward the lower side of the box so as to clear theflanges of the channel-bar when fitted into the housings.

The housings may be variously constructed to engage the wingsdetachably, so as to facilitate the assembling of the parts and theseparation of the same when required for repairs.

To illustrate this feature two constructions are shown in the annexeddrawing, in which the car body is omitted, and only the box-mountingisshown. I

Figure 1 is a perspective view of a channel-bar with one of theaxle-boxes fitted thereon, and the housing forked or open at the lowerside; Fig. 2 is an inverted plan of the parts shown in Fig. 1; Fig. 3 isa cross-section of the channel-bar shown in Fig. 1 online 3-3 in Fig. 2;Fig. 4 is a Specification of Letters Patent;

Patented Oct. 12, 1920. 1920.- Serial No. 400,672. i

View like. Fig. l with one side; and Fig. 5 is across-section of thesame at one edge of the socket in the housing.

The channel-bar is formed of a plate a with flanges a at its edges;these flanges stiffen the plate and afford attaclnnent of the housingsto the bar.

designates the car-axle, with a carwheel C upon one end. For want ofroom upon the drawing, the car-wheel is omitted from the opposite-end.

The body of the axle-box is designated D, and its upper part is fittedbetween the flanges a, and provided with a-seat 7) to rest or bear uponthe plate a. Such seat ismade convex on top, crosswise of the box, so asto rock lengthwise, to adjust itself to the axle and platesimultaneously.

lVings 0 are projected from the sides of the body D, below the level ofthe flanges a, and the housings are attached to the outer sides of theflanges to embrace these wings, and hold the box from longitudinalmovement.

The housings have each a foot-plate ctattached to the flanges a byrivets cl, and an arm or arms extended downward from the edge of theflange to form the sockets which loosely embrace the wings.

In Figs. 1 to 3 the housing is formed with two arms it having a socket Ebetween them to receive the wings of the axle-box.

the housingopen at In these figures, the lateral thrust on the box isresisted by lugs or. ears 6 projected from' the sides of the body nearlyto the flanges.

' The box and its wings and lugs are constructed, as shown at e, toclear the flanges a and housings h, 72. to permit the boxes to adjustthemselves automatically to the axle. This construction avoids thenecessity of any mechanical adjustments, or the proyision of any movableparts to effect adustments.

A lock-bar f is attached to the ends of the arms h and touches the undersides of the wings to lock or retain the wings in the housings.

The lock-bars are held in place by crossbolts 9 which pass through thearms and lock-bars, .and extend below the body of the box; thussupporting it firmly.

. The box can be taken from the channelbar by withdrawing the bolts andremoving the lock-bars.

The housings sustain the wings beneath the flanges a and hold the boxesfirmly from end thrust, without outting'into the flanges to form atransverse shoulder.

In Figs. 4 and 5 the housing is open at one side and each wing is heldin placeby the horizontalarm if of the housing alongthe lower side ofthesocket E. I

The vertical arm k of the housingresists end-thrust upon the axle, andend-support in both directions is secured by applying the housings tothe opposite ends of channel-bar in reverse positions. 1

In Fig. 5, the seat I) on top of the body D is extended nearly to theinner sides of the flanges a to resist lateral thrust, and the Wings 0are extended out from the ends of the seat to project throughthehousings. r

With both the constructions of Figs. 1 to 4 the end-thrust is sustainedwithout notching the flanges a.

With both of the constructions showman eflicient support andself-adjustment otthe axle-boxes are secured with the use of ordinarychannel-bars and rough-castings, thus 'PIOClHClIlg a very cheapconstruction.

Having thus set forth the nature of the invention what is claimed hereinis:

1. Ina car-axle mounting, the combination, with a channel-bar, ofhousings secured to the flanges of the bar, and axleboxes arrangedbetween the flanges, and having wings projected outward through the saidhousings.

2. In a car-axle mounting, the combination, with a channel-bar, ofhousings secured to the flanges of the bar, and axleboxes arrangedbetween the flanges and having Wings projected outward throughthe'housings beneath the said "flanges.

V 3. In a car-axle mounting, the combination, witha channel-bar, andaxle-boxes arranged between the flanges and having wings extendedoutwardly, of housings attached to the outer sides of the'flangesiandsocket open at the bottom, and one of the wings fitted thereto, and alock-bar connectlng the arms below the wing and secured by bolts throughthe arms and lock-bar.

6. In an axle-box mounting, the combination, with a channel-bar, ofhousings secured to the flanges of the bar, and axle boxes fittedbetween the flanges, and having each a convex seat fitted to the plateof the channel-bar, and extended nearly to the flanges 'to resistside-thrust, and having wings extended beyond the ends of the said seatand embraced by the said housings;

In testimony whereof I have hereunto set my hand.

JAMES E. BUSHNELL.
